Description

Safety standard opener for medical ampoule bottle and use method thereof

Technical Field

The invention relates to the technical field of medical instruments, in particular to a safety standard opener for a medical ampoule bottle and a using method thereof.

Background

The ampoule bottle is a small glass container for containing liquid medicine, has the capacity of 1-25 ml generally, is commonly used for liquid medicine for injection and is also used for packaging oral liquid. The medical ampoule bottle consists of a bottle body, a bottle neck and a bottle head, and the method for correctly opening the ampoule bottle in medicine is specified in basic nursing science: and (3) bouncing the bottle head liquid medicine to the bottle body, scratching a saw mark at the neck of the ampoule bottle, disinfecting with a 75% ethanol cotton swab, and breaking the head of the ampoule bottle. However, this method has many disadvantages: 1. the operation process is complicated, and because the clinical medicine dispensing workload is large, the number of the ampoule bottles needing to be broken off in a short time is large, the operation process is difficult to be strictly implemented in actual work; 2. in the breaking process, if the force applied by medical staff is too small, the bottle head cannot be broken off, and if the force applied is too large, the fingers of the medical staff are easily punctured by the glass slag during breaking, so that unnecessary injury is caused; 3. glass fragments and grinding wheel particles at the scratch position easily fall into the bottle to pollute the liquid medicine; 4. because the grinding wheel is very small in size and inconvenient to take, the grinding wheel is easy to lose after being used, and the work of medical staff is influenced.

In order to reduce the risk of injury to an operator when the ampoule bottle head is broken after saw marks are marked at the bottle neck by using a thin grinding wheel, for example, the medical ampoule bottle safety standard breaking device with the authorization notice number of CN106185758B has the advantages of standard ampoule bottle breaking operation, high breaking safety factor and high operation efficiency. However, this device also has the following disadvantages: (1) because the emery wheel piece is fixed to be inlayed at telescopic lower extreme opening inner edge of stereoplasm, the emery wheel piece can not be too closely from ampoule body, and ampoule itself (especially bottleneck department) diameter will be less than the telescopic internal diameter of stereoplasm, so carry out the ampoule or the stereoplasm sleeve that the scribing must incline certain angle at rotatory ampoule, emery wheel piece to bottleneck department, will arouse firstly like this: the ampoule bottle and the hard sleeve are difficult to rotate relatively due to the friction between the bottle head and the silica gel sleeve, so that the bottle neck is scratched; secondly, the following steps: the acting force of the grinding wheel and the bottleneck is the force generated by the action of the fulcrum, so that the bottle head and the bottle body are broken and broken in advance, and the fingers of a doctor are scratched; (2) this degassing unit is disinfected by catch bar promotion aseptic cotton arrival bottleneck mar department, because the bottleneck department of ampoule is inside sunken, and the upper and lower department of depressed part all is outside outstanding part, and the internal diameter is obviously greater than the internal diameter of depressed part, so has aseptic cotton and bottleneck department mar contact insufficient and the incomplete hidden danger of disinfection that leads to the fact.

(3) the first driving lantern ring (5) is rotated to descend along the hard sleeve (1) until the inclined opening end of the connecting column (6) drives the exposed end of the inserting column (2) to tightly support the grinding wheel piece (3) and the positioning sliding piece (1b) at the bottle neck (15c) of the ampoule bottle (15);

(4) the bottle body fixing lantern ring (16) is held by a hand, then the bottle body (15b) of the ampoule bottle (15) is rotated, and the grinding wheel (3) cuts the bottle neck (15c) to form a bottle neck scratch;

(5) after the cutting is finished, manually pressing the extrusion end (4b) of the disinfection rod (4) inwards until the cleaning and disinfection end (4a) is contacted with the bottle neck scratch, and disinfecting the bottle neck scratch;

(6) after the disinfection, the knob (14) is rotated, the threaded rod (12) drives the arc-shaped push plate (13) to push and press the bottle body (15b), so that the bottle head (15a) is broken off from the bottle body (15b), and the ampoule bottle (15) is opened once;

(7) the opened bottle body (15b) is taken out, then the elastic end cover (19) is covered, the thumb presses the elastic end cover (19) downwards, the first elastic bulge (20) and the second elastic bulge (21) downwards extrude the bottle head (15a) sleeved on the fixed lantern ring (8), and the bottle head (15a) is pushed loose and is convenient to take down.
